cation, reference being had therein to the ac-.

companying drawings.

The invention relates to electrically-heated sad irons and consists incertain features of construction as hereinafter set forth.

In the drawings, Figures 1 and 2 is a perspective View of the partscomposing the iron unit.

detached; and Fi 3 is a vertical longitudinal section throng the iron.

My improved iron is composed of a flat base section A to which theheating elements are directly attached, and a superposed hood section Bhaving a handle C secured thereto.

The heating element is preferably formed of a plurality of units, eachconsisting of lan'iinatedmetallic conductors and alternate insulators,and'these are preferably alternate sheets of metal foil and mica, asindicated by D and D, corn osing a unit E. These units are clam eddlrectly to the base A, preferably by orming lugs F projecting upwardfrom the base, which are machined or otherwise -fixed to form a'goodcontact with the unit. As shown, three of the units are attached tothe'base, and are arranged with one unit extending centrally of the basefrom the forward pointed end thereof and two of the units arranged uponopposite sides of and overlapping the rear portion of said forward hisproduces a com aratively uniform distribution of heat, w ile the centraland forward units extends the heating'eifect to the point of the iron.

The three units are preferably connected in series, and preferably bymetallic bridge pieces G extending between the adjacent or overlappingportions of the units. The terminal connections are attached to theopposite side units and are arranged to pass upward and rearward throughapertures in the hood section 3. For this purpose, each terminalpreferably comprises a section H formed of thin flexible and resilientmaterial, having at its up er end a terminal post or pin I attached tereto, said 0st having a ortion J which is surrounded by an insulatmgsleeve K and a threadedportion L having a nut M thereon. The inner endof the post has a collar or shoulder N and the insulator washers O andP, formed of mica or other suitable material, are also sleeved upon theost. the post I will pass through the apertures Q in the rear end of thehood B, the insulator sleeves K fitting in said apertures and thewashers O and P bearing against the hood on the inner and outer facethereof. The nut M is then engaged with the threaded portion L of the0st to clamp the latter firmly to the hood. hus the externallyprojecting terminals are permanently attached to the heating element,and in such amanner as to errnit of quickly removing the hood, whic i issecured to the base A by a single bolt R.

The units E are clamped to the base by suitable means, such as the .capscrews S, and cap plates T are preferably placed over each unit to holdit in position and also to form the heat e ualizer.

The whole arrangement is such that In use tie terminal posts I may beengaged with a socket fitting U, which is attached to the cord orflexible connection V.

What I claim as my invention is: 1. An electrically-heated sad ironcomprising a base section and a removable hood section, a heatingelement secured to said base section within said hoodand a terminalpermanently attached to said heating element and projecting outwardthrough an aperture in said hood.

2. An electrically-heated sad iron comrising a base section, a hoodsection,- a heat- 1ng element secured to said base section within saidhood, a terminal permanently attached to said heating element pro'ectingoutward through an aperture in. sai hood and insulated clam ing meansfor mechanically attaching sai terminal to the hood.

3. An electrically-heated sad iron comprising a base section, a hoodsection, aheating element attached to said base within said hood and aterminal permanently attached to said heating element having a flexibleand resilient portion and a rigid portion pro- 'ecting outward throughan aperture in said ood, means for clamping said rigid portion to saidhood and means for insulating the terminal from the hood.

4. An electrically-heated sad iron comprising a pointed base section, aplurality of electrical heating units clamped to said base, one of saidunits being arranged centrally and extending adjacent to the forwardpoint of said base and a pair of units being arranged and overlappingsaid central unit, terminal connections to the opposite members of saidpair and bridge connections between said central unit and the unit onopposite sides thereof.

5, An electrically-heated sad iron comprising a base section, a heatingelement clamped to said base, a hood section detachable from said basefor inclosing said element, terminal connections permanently attached tosaid element and projecting outward through apertures in said hood,means for securing said hood to said base and insulated clamping meansfor securing said terminals to said hood.

6. An electrically-heated sad iron comprising a base section anda-removable hood sec-- tion, a heating element secured to said basesection within said hood, terminals permanently connected to said baseand passing outward through apertures in said hood, an

insulated clam for rigidly attaching said terminals to said 00d, and asocket fitting for enga ing the projecting portion of said termma S.

7. An electrically-heated sad iron comprising a base section, aremovable hood section having apertures therein, means for securing saidhood to said base, a plurality of heating elements attached to said basewithin said hood, terminals permanently attached to said heatingelements and projecting out through the apertures in the hood, andinsulated clamping means for securing said ter minals to said hood,

In testimony whereof I affix my signature in presence of two witnesses.
